Hi there...i have this pack and it holds the mammut 320 probe, which packs to 44cm, (the voile shovel and handle are in there too), with plenty of room to spare...so you should be right. its pretty voluminous...the rest of the pack easily fits skins, first aid kits, spare gloves, 500ml thermos, down jackets, sol bivvy's x2, emergency kits, food packs, etc...its a sizeable pack...cheers ss
